TOYOTA PRODUCTION SYSTEM AND OPERATIONAL EFFICIENCY: CONTRIBUTION OF LEAN TOOLS TO WASTE REDUCTION

Abstract

This study analyzes how Toyota Production System tools can contribute to operational efficiency and waste reduction in organizations. The research adopts a qualitative and descriptive approach based on a bibliographic review of books, scientific articles and academic studies related to lean production. The discussion focuses on Just-in-Time, Jidoka, Kanban, PDCA and Kaizen as complementary practices. The reviewed literature indicates that synchronizing production with demand reduces inventories and waiting time; built-in quality limits defects and rework; visual management improves flow control; PDCA structures problem solving; and Kaizen supports continuous improvement. The findings also show that the strongest results emerge when these practices are managed as an integrated system rather than as isolated tools. It is concluded that Lean principles can improve process predictability, resource utilization and value creation, provided that implementation is supported by clear standards, reliable information and employee participation.
